I have no idea about what the Pathfinder project is. (If it is a package
for Windows I have no means test it)

My patch does not change any projection code in GRASS, it just expands
g.setproj so the user can set up a location in any of the 76 supported
projections. The projection code originate from the USGS PROJ4 package,
and has been part of GRASS for a long time, but only a few of the possible
projections have been used by g.setproj sofar. 

The ellipsoid used affects the conversion results, so when comparing
results to those another projection program you should always take the
ellipsoid into consideration.

By the way, patching with the -b flag, i.e. 'patch -b -p1 < patch-xxx-xxx'
creates back-ups of the changed files, so you can revert the patch easily
with  'patch -R -p1 < patch-xxx-xxx'
